简介:在土壤外壳开发的降雨事件运动的影响经由实验室实验和基于物理的水文学反应模拟被调查。流量和土壤水内容数据被分析以便在许多降水条件下面学习不同外壳的开发时期。当一个稳定的状态,能被雨点影响的一个扩大时期打破,被发现为外壳并且,随后存在时,结果证明显著地改变的外壳的形成玷污浸透的水力的电导率(K)和流量流量特征。在K的减少为下游动人的事件象86%一样高,并且72%为在上游动人的事件,说明降雨运动的方向比降雨紧张和持续时间在外壳形成上有更重要的影响。同样下游动人的降雨事件可以比那些移动有更大的效果在上游,在雨点影响前的一个depositional外壳的发展可以在决定最后的K价值起一个重要作用。

简介:在过去的地震基于海底的电报的表演,在海床差错运动下面决定电报性能的一个分析方法在这篇论文被建议。首先,海底的电报的地震损坏的普通类型被总结,它包括差错运动,海底的山崩和海床土壤液化导致的海床排水量,等等。损坏类似于观察到跟随陆地地震的埋葬的管道的损坏。2006年12月26日的Hengchun地震被用作案例研究。M7.2地震在20:26北京时间在华南海发生了,并且引起了14国际海底的电报切断并且碎。结果证明建议方法预言类似于在Hengchun地震观察了那的损坏。基于水深度和海底的地震的大小的影响的参量的研究,阻止损坏到海底的电报的反措施被建议。
简介:让G没有固定的点在的一个集合上的一个排列组,和m是一个积极整数。然后,G的运动被定义为行动(G):=supG{|Gg\G|g?G}行动(G):=\mathop{\sup}\limits_\Gamma\left\{{\left|{\Gamma^g\backslash\Gamma}\right|\left|{g\inG}\right}\right\}。它被Praeger显示出如果行动(G)=m那时|3m+t1,在t是G轨道在上的数字的地方。在这份报纸,有有最大值的度3m+t1的所有不及物的排列组跳了被分类。确实,她问题的一个积极答案是否上面的界限|=3m+t1为|为每t是锋利的>1被给。
